OPTION B-------- all elements of first and fourth columns
Since x coordinates of z matrix indicates rows and y coordinates indicates columns. And in question y coordinates are given hence they are all elements of first and fourth columns

Write a program that reads a matrix from the keyboard and displays the summations of all its rows on the screen. The size of matrix (i.e. the number of rows and columns) as well as its elements are read from the keyboard. A sample execution of this program is illustrated below: Enter the number of rows of the matrix: 3 Enter the number of columns of the matrix: 4 Enter the element at row 1 and chd umn 1: 1...

1. Define a matrix PQ. component by component, using matrix subscripts, that satisfies the following: Matrix has 2 rows and 4 columns Each matrix element is equal to that element's column number plus its row number (assuming the Mathcad default of columns and rows start counting at the number zero) Show the resulting matrix

Design a class to perform various matrix operations. A matrix is a set of numbers arranged in rows and columns. Therefore, every element of a matrix has a row position and a column position. If A is a matrix of five rows and six columns, we say that the matrix A is of the size 5 X 6 and sometimes denote it as Asxc. Clearly, a convenient place to store a matrix is in a two-dimensional array. Two...

C++ , no ptrs or struct Solve a system of equations using the Gaussian Elimination technique. The matrix will be 10X10 or smaller and will contain floats. Then read in the matrix. Then read in the original answer column (see below for example). Then using the element location 1,1 of the matrix (note I am using the mathematics convention of starting numbering at 1), you will change row 1 and also eliminate the other elements in column 0 using Gaussian...
